' Application filed ANovember' 23, 1910, Serial No. 593,906. Renewed March 9, 1912. Serial No.l 682,758.

Be it known that we, WYLE T.l WILSON and ALBEN B. STARE, both citizens of the United States, the former residing at Philadelphia, county of Philadelphia, State of Pennsylvania, the latter residing at New York, county lof New York, State of New York,'have invented certain new and useful Improvements` in Tube-Winding Machines; and we do hereby declare the ollowing to A. be a full, clear, and exact description of the invention, such as will enable others skilled in the'art to which it'appertains to make and use the same.

This invention relates to tube winding machines, and has for its object to produce a machine which will be more simple in con- A struction, and one which will require less attention thanthose heretofore proposed. 4v"To these ends the invention consists-in the novel details of construction and combinations of partsmore fully hereinafter disclosed and particularly pointed out in the claims. y n

`Referring to the accompanying drawings forming a part of this specification in whichv chines in common use support the winding belts upon'adjustable arms, in order to vary the angle between said belts and the mandrel, and when a given size of tube is being' made, these cross arms areconstantly getting out of order and giving a great deal of trouble in returning them to their. proper adjustments'. So long as tubes of a fixed diameter are to be made, however, there is no necessity for `havin the' winding belts adjustable, and,v there ore, if only one size of tube should bel desired, the windin belts as well as the mandrel could be ma e practically non-adjustable, and therefore. al1 the complicated power 4connections with the cross arms which 'are new "employed, could be eliminated.

In lthe machine now to be described, we do away with the above complicated connections with the cross arms, and at the same time we provide for a limited adjustment which will enable the diameter of the tubel tobe varied within certain limits.

1 indicates any suitable base on which the machine `is supported; and 2 the head for the mandrel rigid with the extension 3 which is pivoted at 4 to the base 1.. The mandrel 5 is also rigid with the head 2, so that when the pivot 4 is fixed, the said mandrel remains fixed.

6 represents standards secured tothe base l and carrying the pulleys 7 for the winding belts 8, as shown.

9 represents a power shaft provided with the gears 10 engaging the gears 11 carried by the shafts 12- of the pulleys, which are fixed as shown to the base plate 1.

The belts 8 pass around the mandrel 5 in the usual manner,.and also around the ulleys 13 carried by the shafts 14, suppdrted in the blocks 15 adapted to slide in the ways 16 and adjustable in said ways by means of the screws 17 and hand wheels 18. A screw 19 passes through an extension of said ways atan angle to the screws 17, and through the hand wheel 2O adjusts said blocks 15 as well as the slide ways 16 longitudinally of the mandrel as willbc readily understood.

From the mechanism so far disclosed, it

.is evident that by loosening the pivot 4 the mandrel 5 can be adjusted around said pivot and that by operating the hand wheel 20 the belts can be correspondinglyadjusted, while by operating the hand wheels 18,' said belts can be tightened or loosened as may be desired. A

In practice, as shown in Fig. 3, the mandrel extends some distance beyond the base 1 and is preferably provided with a roller device for support-ing its end portion be yond the belts. Also attached .to said base 1 is a. supporting plate 26 for the cut-off mechanism which in this instance may consist of a saw 27 supported. by a carriage 28 and receiving power through the pulleys 29 and 30 in a mannerwell known.

31 represents ya means for adjusting 'the' mechanism slide.

cut-ofi' mechanism, and 32 and -33 represent rods upon which certain portions of said 'Since the said cut-oif mechanism forms no part of the present in- -vention, it is not herein more fullydisclosed.

34 represents the usual paper strips which are fed to the mandrel through the guides 35, and 36 represents a pulley for applying power to thel shaft 9.

It is evident from the mechanism lnow disclosed that tubes of a lixed diameter and employing strips 34 of a uniform width may be wound upon the mandrel 5. It is further evident that should it be desired to vary the widths of theV strips 34 as well as the diameter of the tubes within limits, that the adjustment of the pulleys 13 and of the mandrel around its pivot 4 will provide for such variations, and yet the complicated connections between the pulleys 7 and the power that have lbeen heretofore used are not employed. Further it will be observed that the fixed pulleys 7 are of a much larger `diameter than the pulleys 13, and it results from this, `that the said pulleys 7 .provide a much greater frictional or C' iving surface for the winding belts 8 .than uo the pulleys 13. In fact, in those cases where it is desirable to do so, the fixed pulleys 7 are made vsufficiently large to entirely drive the belts pulleys 7 and 13'of equal size, and also one which is capable of making tubes of sizes ldiffering sufficiently for a large number of purposes. While in such a machine the pulleys 7 take up considerable space on one side of the mandrel, the pulleys 13 are so small on the other side that all the necessary room for manipulating the paper is provided. It. should alsobe observed that the pivot 4 being located ina vertical plane passing between the belts, the strains tending to swing said mandrel on said pivot are neutralized,

which would not be the case if said pivot were locatedto one side of said belts.' It will be further observed that the entire adjustment of the belts maybe obtained from the swiveled mandrel when desired by loosening the pivotal bolt 4 and suit-ably adjusting thevmandrel. Insuch case the longitudinal adjusting screw 19 need not be used aixd therefore could be omitted, thus y still further simplifying the machine.

Since'those skilled in the art may vary the arrangement of parts and the details' of .construction Without departing from the spirit of our invention, we do not wish to be limited to such features except as may be required by the claims.
